Sorry, here the version information:
ONTAP 9.3P1
PSTK 9.6 (Installfile was named NetApp_PowerShell_Toolkit_9.7.0.msi, OntapiPS.dll 14.11.2019, Product Version 9.7.0.0)
the command I used is
Get-NcNfsExport -VserverContext svm_xxxxx_nfs | select -ExpandProperty securityrules
First output is this (edited):
Pathname SecurityRules
-------- -------------
/ {False, False, False, False...}
Anon : 65534
NcController : clustername
Nosuid : False
ReadOnly : {several IP addresses and networks...}
ReadWrite : {several IP addresses and networks...}
Root : {several IP addresses and networks...}
SecFlavor : {sys}
NosuidSpecified : True
Wrong are the entrys at ReadWrite and Root. They have to be empty.
